question about Horizons 2 I can blind scan and pickup something very strong and hold good signal strength on a transponder, then i check something else I've found usually a news feed or some reporter and signal is very good but quality is all over the place and I get breakups and weak signals on another transponder. Why are some perfect and strong, and others on same satellite same polarity very week and hard to get. Can they spot beam the signals to certain parts of the us? Thanks, Chad
